PWG1 - ITIN PWG2 - ITC PWG3 - Tokenbase






PWG1 supports and advises the ITSA Secretariat on the development and implementation of ITIN as token identification standard. The working group will thus focus for instance on technical aspects of ITIN, the ITIN issuance process, and on strategies for the implementation of ITIN through partnerships with exchanges and token issuance platforms. As ITSA participates in the ISO Working Group on the development of a globally accepted Digital Token Identifier (ISO TC 68/SC 8/WG 3), the Working Group Head of PWG1 will collaborate closely with the ITSA Secretariat as well as ITSA’s representatives in the ISO Working group in order to align the development of ITIN with the work of ISO and its members.


Exemplary topics


1. How can a technically and economically efficient two-point-identification be implemented?
2. What functionality should the ITIN registry offer?
3. What partnerships should be prioritized in order to establish ITIN as practicable market standard?
